Abstract

The utility model belongs to the technical field of a guard-rail net, which discloses a connection column used for connecting the guard-rail net. The utility model has the main technical scheme that the utility model comprises a cylinder-shaped column body, a connecting rib, a left hook plate and a right hook plate, wherein the cylinder-shaped column body, the connecting rib, the left hook plate and the right hook plate are bent and formed by integral sheet material, and the two lateral surfaces of the sheet material are provided with a plurality of concave openings to form a notch between the hook plates. Because the side surfaces of the column body are provided with the hook plates, the column body and the hook plates are shaped by the integral sheet material through a cold bending roller press, the section of the column body forms a regular class semi-ellipse, a rectangle or a triangle, and the connection column for the guard-rail net has the advantages of simple structure, convenient installation and operation, and large anti-bending strength of the column body. In addition, the hook plates of the connection column for the guard-rail net is bent toward the inner side along an arc line to be matched with a protuberance on the straight edge of the class semi-elliptical column body, the utility model effectively prevents tools from prizing, and the security of guard-rails is ensured; meanwhile, the perfect streamline appearance can be formed.

Description

A kind of guardrail net joint pin

Technical field

The utility model belongs to the guardrail net technical field, relates in particular to a kind of joint pin that is used to connect guardrail net.

Background technology

At present, locate, adopt guardrail net to isolate mostly at speedway, railway, plant area's enclosure wall etc.And guardrail net mostly adopts a plurality of net sheets to connect through joint pin, by screw, rivet or welding, makes in installation process between net sheet and joint pin, and installation procedure complexity, efficient are lower.The patent No. is that 03257722.2 notification number is the syndeton that the utility model patent of CN2625506 discloses a kind of guardrail net, but owing to be structure bonding or that be welded as a whole between the round column of the syndeton of this guardrail net of formation and linked network hook, therefore, though the guardrail net joint pin of this structure has solved the low problem of installation effectiveness when using, but itself process extremely inconvenience, and tamper-resistant function is bad.

The utility model content

The purpose of this utility model just provides a kind of easy to process, simple in structure, good looking appearance, installs and uses all a kind of easily guardrail net joint pin.

For achieving the above object, the technical solution adopted in the utility model is: a kind of guardrail net joint pin, comprise tubular cylinder, dowel and left and right hook plate, described tubular cylinder, dowel and left and right hook plate are that the sheet material of one bends moulding, and there is the breach between some recesses formation hook plates the two sides of described sheet material.

In addition: described tubular column cross section is class semiellipse shape; Rectangular shape in described tubular column cross section or triangular shape; Described hook plate is a plurality of, and along described cylinder vertically, with the gap distribution that matches with grid hole; Breach between described hook plate is " U " shape; Breach between described hook plate is a triangle or rectangular-shaped.

A kind of guardrail net joint pin provided by the utility model compared with prior art, have the following advantages: one, because at column side face dowel, hook plate, and and described cartridge type cylinder by the sheet material of one through the moulding of clod wash roller, therefore make the simple in structure, easy to install of guardrail net joint pin; Its two because the cross section of cylinder be class semiellipse shape, the rectangular-shaped or triangular shape of rule, the side direction of cylinder is elongated, and makes the flexural strength increasing of cylinder; Its three because that hook is divided into by breach is a plurality of, and along described cylinder vertically, evenly distribute with the interval of matching, during use, between hook plate, pass all horizontal bars of net sheet with grid hole, hang on the vertical muscle of net sheet, increased the bonding strength of net sheet and joint pin; Its four, hook plate bends towards the inboard along camber line, matches with class half elliptic, cylinder straight flange rectangular-shaped or triangular shape, effectively prevents prizing of instrument, guarantees the safety of guardrail, simultaneously can also form perfect sweeping appearance.

The specific embodiment

Be described in further details below in conjunction with the structure and the use principle of accompanying drawing a kind of guardrail net joint pin of the utility model.

As shown in Figure 1, the guardrail net joint pin comprises that cross section (as shown in Figure 2) is half elliptic tubular cylinder 1 of class and the left and

right hook plate

2,3 that is positioned at this column sleeve body side surface, and 1 of hook plate and cylinder are connected by dowel 4.Tubular cylinder, dowel and the hook plate that constitutes this guardrail net joint pin be the both sides of one have recess sheet material 5 through the moulding of clod wash roller, recess constitutes the breach 6 between hook plate relatively.This breach 6 can be " U " type breach as shown in Figure 5, and the mechanical strength of the joint pin of this shape breach is bigger; Also can be triangular shape breach or rectangular opening as shown in Figure 6, its processing be convenient relatively.

For tension and the collapsoing strength that improves cylinder, the tubular cylinder cross section of tubular cylinder 1 can also be designed to as Fig. 3 or rectangular-shaped or triangular shape as shown in Figure 4.The tubular cylinder processing of rectangular-shaped or triangular shape is simple relatively, when wherein cross section is the tubular cylinder processing of triangular shape, saves sheet material under the situation of mechanical strength more than 10% satisfying.

When installing and using, as shown in Figure 7 guardrail net joint pin 7 is fixed, the vertical muscle 10,11 in the limit of two guardrail net sheets 8,9 snaps in respectively in left-hand and the

dextrad hook plate

2,3, the

horizontal bar

12,13 of guardrail net sheet 8,9 just in time embeds and rides over indentation, there simultaneously, with the two directions tension of guardrail net sheet 8,9, carry out the installation of next fence post again.
